You can send VLAN tagged or untagged packets on any interface; obviously, if
you are allowing the host at the other end of the cable to set the tags you
are going to trust them to some degree to do the right thing.

So, no, not just.  From the client side, though, it is most common to tag at
the switch, since that way the client is not part of the trust domain.
